RESERVOIR ATTACHMENT FOR PENS- Specification of Letters Patent.

Patented Dec, 26, 1905 Application filed October 3,1904. Serial No. 227,047.

To all whmn it may concern:

Be it known that I, HARRY RICHMOND CHUBB, a subject of the King of Great Britain, residing at 37 Hyde Vale, Greenwich, county of Kent, England, have invented new and useful Improvements in Reservoir Attachments for Pens, of which the following is a specification.

This invention relates to reservoir attachments or appliances for pens, and has for its object to provide a simple and cheap device of this class.

According to the invention the improved device is in the form of a shallow well or reservoir, which is fitted on the top side of the pen at a suitable distance from its point. The shape of the reservoir advantageously approximates to that of an oval, the length of the oval varying according to the shape of the pen. That part of the reservoir farthest from the point of the pen is suitably attached to a flexible band or clip by means ofa short narrow neck of flexible material, thus enabling the reservoir to be attached to the pen or penholder and secured in its desired position. The bottom of the reservoir is formed by the back of the pen itself, and the movement of the nibs of the pen in the act of writing causes the ink to flow in a steady and uniform manner. The attachment is preferably made integral and of soft rubber; but it may be made in other ways and of other material which will allow freedom of movement to the reservoir without impairing or interfering with the natural flexibility of the nibs of the pen. The pen proper may be formed with a recess on each side for receiving the band or clip in order to retain the latter in the proper position. 1

In the accompanying drawings, Figure l is an elevation of a pen drawn to an exaggerated scale and having applied to it a reservoir made according to the invention. Fig. 2 is a longitudinal section thereof. Figs. 3, 4, and 5 are respectively an elevation, a plan view, and a longitudinal section of the reservoir attachment. Fig. 6 is a view similar to Fig. 1, showing a slightly-modified construction in which the edges of the pen are recessed, and Fig. 7 is asimilar view of the pen shown in Fig. 6 with the reservoir attachment removed.

(t represents the well or reservoir, which is placed upon the top of the pen 6 at the root of the nibs thereof. This well is in the form of a short piece of tube, preferably of the somewhat oval shape shown, and when in place upon the top of the pen 6 has its bottom formed by the surface of the said pen, so as to provide in conjunction with the said pen a shallow cup.

0 is a flexible band or clip which is attached to the part of the reservoir a farthest from the point of the pen by a narrow flexible neck portion 0 which is preferably very short, as shown, so that the reservoir is close to the supporting device or clip. The clip 0 is adapted to he slipped over the pen or penholder to hold the reservoir in proper position on the back of the pen, This neck portion 0 is flexible to permit the reservoir to adapt itself to the movements of the pen, but does not act in any sense like a spring or exert any pressure upon the back of the nibs. I have shown the reservoir, the attaching band or clip, and the connecting flexible neck as formed integrally of soft india-rubber, and this is my preferred manner of forming it.

Figs. 6 and 7 illustrate the arrangement before referred to, wherein the pen 6 is provided with a notch orrecess (Z on either side,-these notches or recesses being of a length and depth to receive the clip 0, as clearly shown in Fig. 6.

I am aware that it has been contemplated to provide a pen with a spring bearing upon and affecting the operation of the nibs and to provide such a spring construction with a reservoir; but such construction I do not seek to claim, as it is of the essence of my invention that the reservoir shall be flexibly supported upon the pen, so as to allow freedom of movement to the reservoir Without interfering with the natural flexibility of the nibs of the pen.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. A reservoir attachment for a pen, comprising among its members, a reservoir, a supporting device therefor and a short narrow neck of extremely flexible material connect ing the reservoir and its supporting device, for supporting said reservoir upon the nib of a pen without exerting pressure thereon, substantially as described.

2. Areservoir attachment for a pen comprising among its members a reservoir, aclip closely adjacent thereto, constructed to engage the pen, and anarrow neck of soft rubber connecting said clip and reservoir, substantially as described.

8. A reservoir attachment for a pen com- IO the pen and lit in said recesses, a reservoir closely adjacent to said clip, connected thereto by a short narrow flexible neck and supporting the reservoir upon the nibs of the pen Without exerting pressure thereon, substantially as described.
